  • touch it

  • when you like, look at my vid "zündspule", 2 ignition coils with 2000w. 

  • any samples of oscillator relating to that? how much frequency is that guy using?

  • very good

  • an auto relay and a capacitor work just fine for me most ic's and stuff are to unreliable around high voltage only for very short runs

  • GOOD :) View my Video Computer + 2N3055 + Coil.... (Very EASY)

  • DC only for an automotive ignition coil. Then switched on and off rapidly. Thats what the 555 timer is for.

  • Thats how it works. The field in the coil will only collapse and release its energy when it is powered off. Thats why this guy uses the 555 timer. In a car, the spark plug fires when the ignition circuit opens (off), the circuit closes (on) so the coil can build its charge for the next cylinder to fire. When you open and close the circuit several times per second you get the cool arcing effect.

  • Kinda the opposite you might think. You apply power via the + & - terminals, the coil takes on a charge and amplifies the voltage, when power is switched OFF to the coil, the field collapses and dumps its load to ground through the top terminal. A typical 12v coil can put out 30 to 40KV. In order for it to work the power must be repeatedly switched on and off. This guy is using a 555 timer instead of the cars points or electronic ignition switch.

  • what sort of switching circut is that? 555timer?
